Simple yet excellent tool!

Any translation campaigns in mind?

This project may be useful and reach beyond horizons with translations to Arabic, Chinese, French, Russian, Spanish, &c...

It seems that your open-source project does some stuff with Monero.

Are you thinking about adding Polyseed to its features?

Source: https://github.com/tevador/polyseed

Polyseed has a number of advantages over Monero’s standard seeds:

The wallet creation date is embedded in the mnemonic seed. This way you no longer have to worry about restoring your wallet from the correct restore height.
It uses BIP-39 wordlists. These wordlists container shorter and more common words than Monero’s lists.
Polyseeds seeds are quicker to write down and memorize.

I am pleased to announce that the development of this service is now acquired by CPUchain project.

Thank you.
Hello there!

I was about to consider writing about your project here:

⚡ LIST ⚡ FOSS Brainwallets

Are you its lead developer nowadays?
Are you one of its maintainer?

Have you left the project?
8  Bitcoin / Project Development / Re: ⚡ LIST ⚡ FOSS Brainwallets on: June 05, 2024, 04:21:55 AM
Thanks for your reply!

Your project is gonna join the list soon...

In my opinion, brainwallet algorithms are too vulnerable to try to secure with any kind of KDF, since the input is often predictable.
Generating a few (e.g. 9 or +) BIP39 random words + unique salt (e.g. checksum) should be interesting as an experiment. Fewer words to remember (less than standard 12) and not so easy to crack wallet (considering using the WarpWallet implementation or improved version).

Not worthy risking all your savings but it's still an intriguing experiment.

Is it possible (in the near future) to provide a single AppImage file (or single binary file, or single executable file, etc) as a Github-release?

P.S. Your project reminded me of this HTML/Javascript Brainwallet (WarpWallet's fork) turned into a single CLI executable file: https://github.com/moncho/warpwallet

Providing that option would be great for UX!

Last but not least: your CLI BTC msg tool is awesome!

Congratulations and keep it evolving!

Cheers!

Is it possible (in the near future) to provide a single HTML file (for offline usage) as a Github-release (the way Ian Coleman does with his BIP39 project)?

Providing that option users might avoid those annoying dependencies installation procedures...

Sources:

https://iancoleman.io/bip39/

https://github.com/iancoleman/bip39/releases/latest/

BTW your BTC msg tools is a great project: BitcoinMessage.Tools

Congratulations for reaching those results so far...

And keep up the effort!

Just to let you know, ZPyWallet also has brainwallet generation capability, and even for extended private keys, but I haven't written the documentation for that yet.
Good to know that!

I'm gonna take a look at it.

BTW which type of brainwallet algorithm did you choose for that project?

Traditional SHA2 over (user typed) passphrase?

Or

Warp Wallet type (Key Derivation Function: Argon2id, scrypt, bcrypt, PBKDF2)?

There's a bit of a contradiction there. You wrote that you are revoking those addresses, but also that you are using those addresses. When you sign a message using one of those addresses, what are we supposed to do? Wink
Simple: If you receive (p.s. You won't!) a signed message from those "revoked" addresses → ignore that message entirely and its sender!
17  Other / Meta / Re: Stake your Bitcoin address here on: February 14, 2024, 03:14:13 AM
That's the thing: a staked address is meant to prove you're the long-term account owner. Your account is over 10 years old, your staked address was only a few years old.
I never used them anyway. I mainly created and staked them for testing purposes.

Quote
Staking a new one is exactly what an account buyer/hacker would do, it means you can no longer prove you're the long-term owner.
Account buyers/hackers might buy/hack accounts but it's not usual for them to buy/hack bitcoin private keys...

Quote
You're going to be disappointed: there is no "standard" for signing messages from Segwit addresses. Electrum came up with something, but Bitcoin Core can't even do it.
Don't worry about it. Electrum will do just fine! Others (devs) will follow in the future... Wink

I've verified both signed messages. I didn't check where you've posted those addresses before.
I did that before.

They are staked here:

Does this mean you have no valid staked address left?
I'm going to stake a new one soon...
(i.e. I'm going to adopt the newer segwit bitcoin address standard).
